I cannot imagine any more wrong interpretation. ODbL was created just to stop activities like this. with your interpretation you could easily create a private fork: just "extend" osm data with tags like "myproject:name"/"myproject:maxspeed"/... ridiculous. so, for the avoidance of doubt I wanted to say that is definitely a derivative db (from information provided) and not a collective db. michal -- michal palenik www.freemap.sk www.oma.sk _______________________________________________ legal-talk mailing list legal-talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/legal-talk
